Abstract

This paper presents the phenomenon of laminar turbulent transition simulated by modified algebraic intermittency model based on well known k-ω turbulence model by Wilcox for flows in parallel-plate channels. Results of simulations using described model were obtained for low Reynolds numbers 1000≤Re≤75000 with different turbulence intensity in inlet cross-section of the parallel-plate channel. Results were compared to and validated with existing data available in literature both experimental and theoretical. Implementation of described model with pre-processing and post-processing was made using open source software OpenFOAM.
